Mise en place d'un protocole de traitement de données pour l'étude de l'adaptation d'une large gamme de cépages aux évolutions climatiques en Bordelais

Abstract : In relation to the current and future climatic change, possible grapevine variety modifications are being considered in the Bordeaux area. In order to anticipate these modifications, an experiment has been put in place to study the behaviour and adaptation of a wide range of varieties (both French and foreign) to the Bordeaux climatic context. This study generates many data sets that require specific treatment. In this work, a protocol for data management has been established, which will be re-used each year (R scripts). It provides user usable databases from field measurements. As such day of year or sum of temperatures can be obtained, from the phenological data, for the three critical observation stages: bud break, flowering and véraison. The dynamic of sugar ripening of each variety can also be characterised by adjusting the parameters of a nonlinear model to the data. A factorial analysis, also implemented, allows us to identify the main dimensions of variability between the different varieties berry composition after ripeness. Furthermore, the calibration of an Infrared analyzer was initiated with the matching reference measurements values. Finally, this work is placed at the beginning of a long-term study (the plot has only produced grapes since 2011) and as such attempts to structure and anticipate the data processing to come.
